EDWARD PARKMAN BOYD, OF OKLAHOMA, OKLAHOMA.

FIREPROOIE DOOR AND WINDOW.

To all whom it may concern:

Be it known that I, EDWARD P. BOYD, a citizen of the United States, residing at Oklahoma, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Fireproof Doors and Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanylng drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in fire proof openings for windows, doors, etc., and the object in view is to produce a simple and efficient construction of this nature, dispensing with unnecessary materials in the frame, sash and pockets and retaining only such parts as are needed to give required strength and stability.

By the provision of my improved construction, added efficiency is obtained by the reduction of the size of the sash and the frame of the window, and adding appreciably to the percentage of glass compared to the opening in the wall of the building, giving added light and a great advantage to narrow and small windows which arecommonly placed between piers or columns to light rooms.

The invention comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully described and then fined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a front elevation of a fireproof glazed opening and window. Fig. 2 is a vertical sectional view. Fig. 3 is a vertical sectional view showing a modified form of the construction. Fig. 4c is an edge view of a pocket in which the sliding window is adapted to enter, and Fig. 5 is a horizontal sectional view.

Reference now being had to the details of the drawings by letter, A designates a window opening, preferably in a fire proof construction of building, and having a metallic beam B therein with a tongue B. A. transverse metallic beam G forms the top of the window opening and has depending Specification of Letters Patent.

specifically de- Patented Nov. 21, 1911. Serial No. 609,309.

therefrom the ribs C and C The frame D of the window, which is made of any suitable material, is provided with an opening D for the glass or panel E, which is preferably reinforced by wiring, and said glass fits against a shoulder F about the marginal edge of the opening in the frame. A plate H, which may be of one piece or several, is fastened to the sash by means of screws I or any other suitable means and serves to hold the glass against the shoulders of the sash. Said plate H, as will be noted in Fig. 2 of the drawings, extends down below the tongue B at the bottom and at the top above the lower end of the rib or tongue C, thus forming a means for keeping out wind, rain, dust, etc. Said beam B extends laterally and forms the bottom to a pocket J, the opposite walls of which, designated by letter K, are corrugated, as shown clearly in edge view in Fig. 1, the spaces between the corrugations being adapted to be embedded between the construction of the wall by cement, plaster or other composition. The upper beam C also extends through the pocket and forms the top therefor, thus affording means for receiving the window as it is moved within the pocket.

In Fig. 3 of the drawings, I have shown a form of the construction in which the plate N is bent upon itself to form a roll N and the sash O has a plate 0 bent upon itself and forming a shoulder against which the pane of glass Q, is adapted to bear, and said plate 0 is bent to form a roll 0 telescoping within the roll N, forming means for guiding the same as the window sash is moved forward and backward. part of the sash in the form shown in Fig. 3 has a plate R bent upon itself as at R and a roller R is journaled between the plate R and the plate S, which forms a means for holding the outer face of the lower portion of the glass in place.

From the foregoing, it will he noted that, by the provision of this construction of windows for buildings, the entire sash, frame and pocket are of non-combustible material, having an advantage over the usual double hung window in that the entire space may be opened in summer instead of half, and no interference being offered to the shades or curtains as in the event of a casement window opening in or to screens, blinds or awnings if it opened out.

From the foregoing, it will be noted that The lower the whole window or door with the sash, frame and pocket may be assembled at the factory and readily adjusted in place in building up the Wall of the fire proof structure.

It should be noted that the drawings show all sections at full size scale.

What I claim to be new is 1. A fire proof door or window for structures, comprising beams forming the top and bottom of the frame of a window or door opening and having tongues projecting toward each other, a pocket, the top and bottom of which are formed by said beams, the sides of said pockets being corrugated and adapted to be embedded in the wall of a building, a sash grooved to receive said tongues, a plate fastened to the face of the sash and covering the joints intermediate the latter and said tongues and projecting over the edges of the glass opening.

2. A fire proof door or window for structures, comprising beams forming the frame of the window opening and having horizontally disposed beams provided with tongues, a sash, plates bent upon themselves and secured to the opposite faces of the sash, a portion of each plate bent to form a shoulder against which the glass is adapted to abut, the plate at the upper end of the sash bent to form a roll, a fixed plate secured to the upper beam and bent to form a roll in which the first mentioned roll is adapted to telescope, a roller positioned underneath the sash and resting upon the tongue upon the lower beam.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

EDWARD PARKMAN BOYD.
